A full-day high-Andes hike from Cusco to the turquoise Humantay Lake, rising from 3,920 to 4,200 meters. Expect rocky switchbacks, thin air, and dramatic glacial views—great for acclimatized hikers who move steadily.

You step out of the van at Soraypampa and the air is thin, sharp with high-Andes clarity. Peaks slope away in bands of gray rock and scrub; the trail climbs immediately, switchbacking across puna grass and loose scree. After roughly 1.5 hours of steady ascent you arrive at a rim that drops into the startling turquoise of Humantay Lake, framed by snow-scratched ridgelines and the distant bulk of Salkantay.

Wildlife
History
The Humantay basin sits in Quechua territory and has long been part of local pastoral cycles; the lake is fed by glacial melt and has cultural significance for mountain water rituals.
Conservation
Stay on marked trails, do not swim in the lagoon, and pack out all trash—high-altitude wetlands are fragile and recovery is slow.
